I am attempting to install FC4/x86_64 onto an Athlon64 3400+ system. The DVD boots and I reach lilo with no problems. When lilo loads the the kernel/initrd the system does a hard reset. It does not mattre what I type (linux, linux text, linux noapic, linux rescue, ...) the same thing occurs. I am able to boot and install FC3/x86_64 DVD with no problems. I downloaded the updated boot.iso for FC4 from the Fedora ftp site and the same thing occurs. The DVD and the updated boot.iso have different kernel revs. Does anyone have any ideas why the system does a hard reset at kernel load of FC4 when FC3 functions correctly? Thanks! Jeff
